Definitions

  • the subject of the present invention is a lock for closures in general (e.g. doors tilting, curtains, roller shutters and others) of cylinder type, in which the cylinder block of the lock is of a unified type with twist bit, known in the art in this field as "cylinder European”.
  • a first object of the present invention is to make a lock for overhead doors, curtains, roll-down shutters and the like, making use of of a unified type cylinder block with bit rotating, named European cylinder, whose structure must be particularly simple, economical and reliable.
  • An object of the invention is also to realize such a lock in which the mechanisms for the moving locks must be intrinsically irreversible compared to an order of outside.
  • Another object of the invention is to realize such a lock whose actuation must ask for a turn only of the key, and it must not not be impossible even if, due to a accident, locks are worn in one position incorrect.
  • a further aim of the invention is to carry out such a lock which, in cases where this is requested, and without causing complications of structure, can be operated from the inside without using the key, and / or by any means motorized, be it that the key is inserted in the cylinder or not.
  • Another object of the invention is to realize such a lock which is likely to be easily mounted by mechanized equipment.
  • a lock for overhead doors, curtains, shutters scrolling and the like comprising a cylinder block with rotating bit, of the so-called European cylinder type, and including a central gear which controls two side cogwheels which in turn control locks, characterized mainly in that said central gear is a crown gear outside surrounding the cylinder block, mounted rotating along an axis which does not correspond to the axis of rotation of the rotating bit of the cylinder block, and with two teeth facing inwards which limit a notch likely to be engaged by the rotating bit, along a limited arc which corresponds to part of a turn of the bit, both extreme positions of engagement between the crown toothed and the bit corresponding to the two positions extremes, opening and closing respectively, locks controlled by the side toothed wheels.
  • each side gear drives a lock by means of an eccentric pivot engaged in a slot in the lock, which extends perpendicular to the direction of movement of the lock and has a limited length on one side at the axis of rotation of the toothed wheel.
  • the distance of said eccentric pivot from the axis of rotation of the side gear is equal to the half of the bolt stroke between position opening and closing position.
  • the side gears (and therefore also the central gear which is meshed with they) are always stopped at the end of the race in a defined position, in which said pivots eccentric and the axes of rotation of the gears are all in line, at least in one way approximate, along the direction of travel of locks, so they're in one condition neutral point which ensures the irreversibility of the moving locks under actions different from those of the actuating toothed wheels.
  • the pivoting of the toothed wheels is obtained by projecting sectors partially sheared in the lock box, in engagement with interior cylindrical surfaces cogwheels. This reduces the costs of manufacturing avoiding the use, machining and mounting of pivots, and allows free space internal of the central gear, space which must be occupied by the cylinder block.
  • the cover of the lock is attached to the lock box by acting means through plastic deformation of some parts of the box or cover. That too reduces manufacturing and machining costs of the lock.
  • One or more springs can be arranged to act between latches and eccentric pivots lateral cogwheels, in order to stabilize the end positions and to give the user a sensitive perception when said positions are achieved.
  • these springs do not have a operative function, so that their possible rupture or nervousness in no way prejudges the functioning of the lock.
  • the lock includes a box 1 which contains the mechanisms and which is closed by a cover 20.
  • the box 1 and cover 20 are provided with openings 2 and 21 respectively, shaped like a cylinder block of the so-called European type, and intended to receive such a block (which is shown in Figures 1 and 2 only by its periphery corresponding to the opening 2).
  • the box 1 also has an opening 3 for the passage of a screw intended to fix in the box the cylinder block 2, in the usual way.
  • holes 4 for fixing to the overhead door, curtain or other closure intended to be fitted by the lock.
  • each lock 8 is provided close to its outer end of a pivot 10 intended to be connected to the curtain locking means or the like to order them.
  • each lock 8 is provided with a slit 11 perpendicular to the direction longitudinal movement of the bolt, to receive the command.
  • Each lock is controlled by a gear wheel lateral 12 provided with a central hole 13 on the surface cylindrical for its pivoting in the box 1.
  • the pivoting is achieved by means of sectors 7 (in number of three in the example shown) partially sheared towards the inside of the walls of the box 1. These partially sheared sectors have an outer circumference in an arc of a circle and give correct support with freedom of rotation to the wheel corresponding side tooth 12, cooperating with the cylindrical surface of hole 13. Such an arrangement avoids the application of pivots to box 1.
  • Each side gear 12 has a pivot stamped 14 capable of engaging the slot 11 of a lock 8. This arrangement constitutes a crank capable of to control the movements of the lock.
  • the distance radial of a stamped pivot 14 relative to the center of the side gear 12 to which it belongs is equal to half the travel provided for lock 8 corresponding; in this way, a 180 ° rotation of the side gear 12 in one direction or the other causes the corresponding bolt 8 to complete its stroke whole opening or closing.
  • the slot 11 of latch 8 ends on one side at the level of center of the corresponding side gear 12, of so that it limits the rotation stroke to the angle of 180 ° which is necessary.
  • the two lateral toothed wheels 12 engage both with a central gear which consists of a crown with external teeth 15 mounted in the center O 'of the lock and surrounding the seat for cylinder block 2, and therefore the block itself when it is installed in the lock.
  • the crown 15 has a cylindrical inner surface 16 for its pivoting relative to the box 1.
  • the pivoting is achieved by means of sectors 6 (in number of four in the example shown) partially sheared towards the inside of the walls of the box 1. These partially sheared sectors have an outer circumference in an arc of a circle and give correct support with freedom of rotation to the wheel central tooth 15, cooperating with its surface internal cylindrical 16.
  • the ring gear 15 has two teeth 17 projecting towards the interior, which define a notch 18 likely to engage the turning bit from block to block cylinder installed in the lock, the trajectory of which of rotation is indicated in figure 1 by the circle C whose center is O. It should be noted that the wheel central tooth 15 is not coaxial with circle C which represents the trajectory of the bit, the two centers of rotation O 'and O not being coincident.
  • the lock according to the invention does not require necessary no spring, which contributes in considerable measure of its reliability. Nevertheless, one or several springs 19 can be installed, such as the show Figures 1 and 2, to act between at least one of the locks 8 and the pivot 14 of the toothed wheel side 12 which controls the lock itself.
  • a spring so arranged gives confirmation to the user sensitive to the fact that the end position of the locks has been successfully reached. Furthermore she tends to keep this end position stable even in the presence of accidental stress, such as shock or vibration. However, the break possible or the nervousness of this spring does not prejudge in no way of the functionality of the lock.
  • the invention also provides a preferred means of fixing the cover 20 to the box 1.
  • the side walls of the box 1 have notches, each which is provided with a tongue 5.
  • a additional conformation of the cover 20 allows place the latter on the box and then fix by plastic deformation of the tabs 5.
  • the notches provided in the side walls of the box 1 could be provided lateral digging, and tabs cover correspondents could be anchored in these excavations by means of a deformation plastic such as to produce an enlargement.
